Observation 35028: Tuber gibbosum Harkn.
When: 2010-03-23
No herbarium specimen

Notes: This is the true, or spring form, of Tuber gibbosum. It has been called Oregon White truffle in the past, but was first found near San Francisco in the late 1800’s. It can be larger than Tuber oregonense, the other more commercially collected truffle here in Oregon. When mature, the gleba becomes grayish-green, and is much darker, even in immaturity, than Tuber oregonense.
